When you cut your skin, you bleed(流血). If a person loses a lot of blood, he will become ill and may die. Blood is very important. People have always known that. At one time, some people even drank blood to make them strong!
When doctors understand how blood goes around inside the body, they try ways of giving blood to people who need it. They take blood from the healthy people and give it to people who need it. This is called " blood transfusion(输血)". The blood goes from the arm of the healthy person into the arm of the sick person.
But there are two problems. First, it does not always work. Sometimes people die when they have blood transfusion. Later, doctors find that we do not all have the same kind of blood. There are four groups—O, A, B and AB. We all have blood of one of these groups. They also find that they can give any kind of blood to people of group AB. But they find that they must give A-group blood to A-group people and B-group blood to B-group people. I have O-group blood and the doctor told me that I could give blood to anyone else safely.
There is another problem. To give blood of the right kind, doctors have to find a person of the right blood group. Often they can not find a person in time. If they have a way to keep the blood until someone needs it, they can always have the right kind of blood. At first they find they can keep it in bottles for fifteen to twenty days. They do this by making it very cold. Then they find how to keep it longer. In the end they find a way of keeping blood for a very long time.
We call a place where we keep money a "bank". We call a place where we keep blood a "blood bank". One day, when you grow up, you may decide to give blood to a "blood bank". In this way you may stop someone from dying. Or perhaps one day you may become ill. You may need blood. The "blood bank" will give it to you.

Recently, a solar-powered (太阳能动力的) plane took to the sky for the first time. It passed an important test on the way to travel around the world.

The plane took off from an airport in Switzerland. It slowly rose above the fields and into the sky.
“There has never been an airplane of that kind that could fly — never an airplane so big, so light, using so little energy,” said Bertrand Piccard, a leader of the project.
During the 90-minute flight(飞行), the plane did several turns. It climbed nearly 1.6km above the countryside.
Engineers plan to test a night flight before July. Then they will use the results of the tests to build a second plane. They plan to travel around the world in that plane in 2012.
“We want to fly it day and night with no fuel (燃料),” Piccard said.
Piccard and pilot(飞行员) Andre Borschberg will take the plane around the world. They will make a few stops to change places and rest after a long time in the air — and to show off their airplane.
The plane will fly at 70 km per hour on average(平均). That is faster than a bike and slower than a car. The pilots will keep the plane in the air for up to five days at a time.

We students enjoy our school life, but sometimes we feel unhappy.It’s every student’s       dream. At the       of every term, we have six exams.
Last week, I finished my final exams. The math exam was the easiest one of all. Most of the problems were from early exams,so I       it soon. The biology exam was hard. The questions were so difficult       I had to guess the answers to them. And there wasn’t enough       to check every answer. But after the exam, my teacher said I did well in it.
In the computer exam, we had a lot to do. I thought I needed more time, but some of my classmates didn’t think      . They just wrote down the answers quickly and then       games.I didn’t think I could get a good mark in the English exam because it was a little difficult       me and I didn’t work hard enough at English.
In our school, we can       some elective courses (选修课). That means students can learn these courses by       and then take the exam. If they pass, they don’t have to have these courses any more.
Now, I am very glad that all the exams are over. The summer holiday is coming and I will enjoy it.

This past month saw one of the most devastating storms in history brings death and destruction on the Philippines. The number of lives lost is still being calculated, but it is already sitting above five thousand. In the flurryof news about the storm and its after-math, the cries of “I told you so” from environmentalists rang out loud and clear.
  These scientists were especially vocal during the United Nations Climate Change Conference, which just wrapped up in Warsaw, Poland. The timing of the conference and Typhoon Haiyan was an eerie coincidence, but perhaps the concurrence offered a wakeup call for all.
  Christiana Figures, Executive Secretary of the UN Framework Convention on Climate Change (UNFCCC) said, “We are witnessing ever more frequent extreme weather events, and the poor and vulnerable are already paying the price.”
  Scientists claim that storms like Typhoon Haiyan are an inevitable result of the effect greenhouse gases are having on our environment. Environmental analysts claim that rising temperatures around the globe and changing weather patterns are all part of the same problem.
  This isn’t breaking news. We’ve heard the warnings for years. The UN has been hosting the Climate Change Conference since1995.But the changes that need to be made are huge. Added to this, the developed nations and developing countries have competing interests that are difficult to settle. The issue of who takes responsibility becomes difficult to resolve.
  We may feel far away from Poland and resolving conflicts between countries, but we mustn’t feel far away from the issue. When we watch neighboring countries suffer in severe weather, when we hear reports of increasing global temperatures, when we walk outside and find it difficult to breathe the Shanghai air, we know we have a very real problem. So what are we going to do about it? Are we making every-day choices that can have a positive impact? Are we reducing our carbon footprint? Are we choosing to walk, ride a bicycle or take public transportation instead of a car? Are we recycling? Are we turning off the lights and electronics whenever possible?
  The problem is complex, but saving our earth starts with each of us taking simple steps.

小题2:Warsaw isn’t in Poland,is it?
